An iguana is on a stone wall surrounding Templo Murciélagos. For hundreds of years, this Temple of the Bats was the royal residence of the halach uinic. Later it housed other members of the almehenoob, the highest ranking members of the Mayan society. Unlike other Mayan communities, the buildings at San Gervasio were constructed from rough-cut stones. They were then plastered over with a limestone mortar before being painted with vivid colors.
